Free AI email apps: what to check before choosing

Updated September 15, 2026. A free email app does not necessarily include free AI. Check the current plan before relying on summaries, writing assistance, or automatic task extraction.

What does “free” include?

Separate basic email from AI features. Receiving, reading, sending, and connecting multiple accounts may be free while AI has a trial, a usage limit, or a separate charge. A free download is not a promise of free AI.

Check the limits and what happens next

Look for the included allowance, its expiry, and the cost of additional usage. Check whether a trial renews automatically and whether paid access requires a subscription. Compare these details against your actual email volume.

Where FiloMail fits

FiloMail Free includes basic email and multiple accounts. AI summaries, to-do extraction, writing assistance, translations, smart labels and filters, automations, and AI Chat require paid access.

You can subscribe to Filo Plus or buy prepaid AI credits without a subscription. AI usage consumes credits. When you have both, available subscription credits are used before prepaid credits. See current plans and pricing.

Privacy and a practical test

Read the provider’s current data policy and check what content is sent for AI processing. Try a few representative, non-sensitive messages: a long thread, a reply you need to write, and a deadline you need to track. Review the output before using it.

Choose an app based on the work it saves you and the price of the features you actually need. Download FiloMail or explore the Help Center.
